Filed: 1987-10-20
Abstract: PURPOSE: To secure the rigidity for withstanding stresses produced on a beam and to make an entire frame lighter in weight and simpler by making the rigidity of the entire beam where a chain is stretched higher than that of a beam where no chain is stretched. CONSTITUTION: Of right and left beams 11a, 11b, the beam 11a where a chain 30 is stretched has a larger number of reinforcing ribs 15 placed throughout the beam 11 a than the beam 11b where no chain 30 is stretched, so that the rigidity of the entire beam 1a where the chain 30 is stretched is enhanced. Thus, the sufficient rigidity to withstand stresses produced on the beam 11a when a rear wheel 29 is driven by an engine via the chain 30 can be secured. Sine the reinforcing ribs 14 are placed in a large number for the entire beam 11a to enhance the rigidity of the entire beam 11a, an entire frame can be made lighter in weight and simpler than it would be if reinforced only partially.

IPC: H02K5/02
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To provide a motor for driving a disc which can be made thin and can get reduction in vibration at low cost. SOLUTION: At the time of rotation, torque is generated between a magnet 6 installed on a rotor 4 and a coil board 2 installed on a frame 1 and then this motor works as an axial gap brushless motor.

Inventor: SAITO JUN
IPC: H01L21/822
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device having a temperature sensor which can take out a temperature signal at high speed, high accuracy and low cost. SOLUTION: An upper arm pn diode 6 is utilized as a temperature sensor for an upper arm insulated gate type bipolar transistor(IGBT) 1. A constant current is fed from a constant current circuit 10 to the pn diode 6 and an ON voltage thereof is taken out as a temperature signal from a terminal 21. The pn diode 6 is formed on a semiconductor substrate for forming the IGBT 1 through an oxide film. Since the thickness of the oxide film is set at such a level as causing no dielectric breakdown at the rated voltage of the IGBT, cathode 8 of the pn diode 6 can be connected with GND without being connected with the emitter terminal E of the IGBT 1. Consequently, a level down circuit can be eliminated and a temperature signal can be taken out easily.

Inventor: NIINUMA ATSUSHI
IPC: B23K11/00
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To realize fine build-up welding with a high quality without thermal influence on the base material by the build-up welding of the conductive metallic member by conducting a specific amount of a high-current in pulse shape within a specific short time between primary electrode and secondary electrode. SOLUTION: By stepping on a pedal switch 50 once, a solid state relay 15 is turned ON by a control circuit 41, and a capacitor group C1 to Cn is charged. Successively, the capacitor group is discharged by a thyristor 16 by a trigger movement of the control circuit 41. Since this discharged current flows to a primary side of a transformer 17, a low voltage and super high-current (1500A to 18000A) is generated on a secondary side of the transformer 17. This super high-current flows instantaneously from the primary electrode 8 to the secondary electrode 2, and the welding is performed. At this time, in the waveform of the current flowing instantaneously to the primary electrode 8, an energizing time (1/1000 to 20/1000sec) and a current value (1500A to 18000A) are inversely proportional.  When turning ON an autoswitch 51b, and when keeping stepping on the pedal switch 50, continuous welding can be performed.
